To (LZZ whom it may concern:

Be it known that I, AnoLrH F UTTER- KNECHT, a subject of the Emperor ofGermany, and a resident of Pernau, Livland, Russia, practical engineer,have invented a new and useful Improved System of Type- Levers forType-Writing Machines, of which the following is a specification.

This invention relates to improvements in typewriting machines, andparticularly to the arrangement and operation of the type bars.

The object of the invention is to provide type bars which are compactlyarranged and carry type adapted to contact with a pad before printing.

A further object of the invention is to provide two sets of type barscarrying different kinds of type, and in which both sets of type areadapted to strike the same platen.

With the above and other objects in view, the invention consists incertain combinations and arrangements of the parts hereinafterdescribed, and the novel features thereof will be particularly pointedout in the claims.

The preferred embodiment of the inven tion is illustrated in theaccompanying drawings, in which like characters of reference indicatecorresponding parts.

Figure l is a view illustrating my invention; and Fig. 2 shows two setsof type bars in relative position.

a and I) represent a pair of cross levers pivotally connected to a typebar a carrying type T adapted to press against an ink pad F and thenstrike at the printing point of the platen V. The lever a, near its freeend is pivoted to the lower leg of a horizontal Z-shaped rigid support 6and the free end of said lever is bent inwardly and is pivotallyconnected to a link cl which is pivotally connected to the lever Z) nearits free end. The free end of the lever b is pivoted to a bar H mountedon a fixed pivot g and is adapted tobe connected to a suitable key leverfor actuating the type bar 0. The travel of the type T and the positionof the mechanism when the type is in its printing position is shown indot and dash lines in Fig. 1.

Referring to Fig. 2 a lever b has one of its ends pivotally connected tothe upper leg of the rlgid support e and its other end to a type bar 0'carrying type T which may be'of a different language from the typecarried by the first mentioned set of type bars. The type T is adaptedto contact with the upper ink pad F and then strike the same printingpoint on the platen as the first mentioned type. Pivotally con nected tothe type bar 0 is a lever atwhich crosses the lever Z2 and its inwardlybent free end is pivotally connected thereto by a link d. A bar Hpivotally connected to the link a near the link (Z is pivotally mountedas at g and adapted to be connected to a key lever for actuating thetype bar 0. The dotted line in Fig. 2 shows the travel of the type T.

By the above described system of type bars and actuating mechanism,compactness of the parts and uniformity of stroke is obtained, and setsof type in different languages may be carried and either set used atwill.

It is to be understood that slight changes in the form, proportion andminor details of construction may be resorted to without sacrificing anyof the advantages or de parting from the spirit of the invention.

Having fully described my invention, what I claim is 1. The combinationwith a type bar carrying type, of crossed levers pivotally con nectedthereto, one of the levers being pivotally supported ancl having a linkconnected to its free end, said link being connected to the other lever,and means for operating the last named lever to actuate the type bar,substantially as described.

2. The combination with a type bar carrying type, of double curvedcrossed levers pivotally connected thereto, one of the levers beingpivotally supported and having a link connected to its free end, saidlink being connected to the other lever near its free end, and meansconnected to the free end of the last named lever for actuating the typebar, substantially as described.

3. The combination with an ink pad and a platen of a type bar carryingtype nor mally in contact with the ink pad, a pair of double curvedcrossed levers pivotally connected to the type bar, one of the leversbeing pivotally supported and having a link connected to its free end,said link being connected to the other lever near its free end, andmeans connected to the free end of the last named lever for actuatingthe type bar to cause the type bar to strike the platen, substantiallyas described.

4;. The combination with a type bar carrying type, of crossed leverspivotally connected thereto, the free end of one of the levers beingpivotally supported, a link connecting the free end of the other leverto the first named lever, and means for operating said other lever toactuatethe type bar, substantially as described.

5. The combination with an ink pad and a platen of a type bar carryingtype normally in contact with the ink pad, a pair of double curvedcrossed levers pivotally connected to the type bar, the free end of oneof the levers being pivotally supported, a link connecting the free endof the other lever to the first named lever, and means connected to saidother lever for causing the type to strike the platen, substantially asdescribed.

6. The combination with a lower and an upper ink pad and a platen oftype bars carrying type normally in contact with the respective inkpads, and means for actuating the type bars to cause the type to strikethe same printing position on the platen, substantially as described.

7. The combination with a lower and an upper ink pad and a platen oftype bars carrying type normally in contact with the respective inkpads, a pair of crossed levers pivotally connected to each type bar, oneof the levers connected to the lower type bar being pivotally supportedand having a link connected to its free end, said link being connectedto the other lower lever, a pivoted bar connected to the free end of thelast named lower lever, the free end of one of the upper levers beingpivotally supported, a second link connecting the free end of the otherupper lever to the first upper lever, a second pivoted bar connected tosaid other upper lever, and means respectively connected to the lowerpivoted lever and the upper pivoted lever for actuating the lower andupper type bars to cause the type to strike the same printing positionon the platen, substantially as described.

In testimony whereof, I have signed my name to this specification in thepresence of two subscribing witnesses.
